Herbal medicine is medicine made from plants, either the whole plant or sometimes parts of it, for example leaves, flowers, roots or bark. It has been the main source of medicine used by people for thousands of years. There are many herbal traditions around the world, but members of the National Institute of Medical Herbalists are trained in what is often known as 'traditional' herbal medicine, as opposed to Chinese or Ayurvedic herbal medicine.
Herbal medicine has itself developed over the centuries and links can be traced back to Graeco-Roman, Arabic, European and American cultures. Although there is a foundation of traditional use to the practice, modern use also includes current scientific research and Institute members are trained in the same clinical examination skills as conventional GPs.
